radialNetwork

From networkD3 v0.2.13 by Christopher Gandrud

Create Reingold-Tilford Tree network diagrams.

Usage

radialNetwork(List, height = NULL, width = NULL, fontSize = 10, fontFamily = "serif", linkColour = "#ccc", nodeColour = "#fff", nodeStroke = "steelblue", textColour = "#111", opacity = 0.9, margin = NULL)

Arguments

List: a hierarchical list object with a root node and children.
height: height for the network graph's frame area in pixels (if NULL then height is automatically determined based on context)
width: numeric width for the network graph's frame area in pixels (if NULL then width is automatically determined based on context)
fontSize: numeric font size in pixels for the node text labels.
fontFamily: font family for the node text labels.
linkColour: character string specifying the colour you want the link lines to be. Multiple formats supported (e.g. hexadecimal).
nodeColour: character string specifying the colour you want the node circles to be. Multiple formats supported (e.g. hexadecimal).
nodeStroke: character string specifying the colour you want the node perimeter to be. Multiple formats supported (e.g. hexadecimal).
textColour: character string specifying the colour you want the text to be before they are clicked. Multiple formats supported (e.g. hexadecimal).
opacity: numeric value of the proportion opaque you would like the graph elements to be.
margin: an integer or a named list/vector of integers for the plot margins. If using a named list/vector, the positions top, right, bottom, left are valid. If a single integer is provided, then the value will be assigned to the right margin. Set the margin appropriately to accomodate long text labels.
